VULCANIZEB.

Specification of Letters Patent.

Patented Jan. 14, 1919.

To all whom it may concern:

Be it known that I, JOSEPH W. DEAN, Jr, a citizen of the United States,and resident of Pond and State of Missouri, have invented certain newand useful Improvements in Vulcanizers, of which the following is aspecification, containing a full, clear, and exact description,reference being had to the accompanying drawings, forming a partthereof.

My invention relates to new and useful improvements in vulcanizers, andhas for its general object, the construction and application ofavulcanizer which is heated by the exhaust gases of a hydrocarbon engine.The further and special object of my invention is to equip the exhaustmanifold of an engine with a vulcanizer and to have a vulcanizingapparatus ready for use as occasion may re quire.

In the drawings,

Figure 1 is a horizontal sectional view of my improved vulcanizer and ahorizontal sectional view of the exhaust manifold of an engine with apart broken away showing partially in top plan view a portion of anengine.

Fig. 2 is a front elevation of the vulcanizer.

Fig. 3 is an end elevation of the vulcanizer applied to the exhaustmanifold.

Fig. 4 is a transverse section taken on a line 2-2 of Fig. 2.

Fig. 5 is a top plan view of the vulcanizer illustrating an improvedconnection by means of which it may be applied to the ex haust manifold,part of the manifold being broken away.

Fig. 6 is a front elevation of the clamping clip employed in securing myvulcanizer to an exhaust manifold.

Fig. 7 is a transverse section taken on a line 6--6 of Fig. 6. 7

Referring to the drawings, 8 indicates a portion of an engine, 9indicates the exhaust manifold thereof, and 10 indicates my improvedvulcanizer which is cast or formed integral with the exhaust manifold 9,being connected thereto by a neck 11.

The vulcanizer is of rectangular shape, and is provided on the insidewith deflecting plates or baffles 12, which extend from the ends of thevulcanizer inwardly, but are spaced apart in front of the neck 11,leaving a passage way 13.

It will be observed from Fig. 1 that the baflies 12 nearest the front ofthe vulcanizer project inwardly farther than the baffles 12 adjacent theneck 11.

Located in front of thepassage Way 13 is a bafile 14. The purpose of thebaffles 12 and 14 is to distribute the hot gases or heat within, andthroughout the vulcanizer. The distribution of heat being shown byarrows in Fig. 1.

15 indicates screw lugs for closing the core openings. 16 in icates athermometer which is arranged adjacent to the exterior wall of thevulcanizer for indicating the temperature of the same.

Cast on the rear of the vulcanizer are lugs or ears 17, provided withinclined slots 18, and cast on the front of the vulcanizer are catchesor lugs 19. Mounted in the slots 18 is a rod 20, and mounted on the rod20 is a press frame 21. The press'frame 21 being provided withperforated arms 22, in which is mounted the rod 20, and by this meansthe press frame 21 is hinged to the vulcanizer. The press frame 21 isprovided with depending arms 23, carrying hooked portions 24, which areadapted to engage with the hooks 19.

25 indicates a press plate, the same being countersunk as at 26, inwhich is located a sheet of asbestos 27. Mounted in the press frame 21is a screw 28 provided with a handle 29. The lower end of the screw 28is mounted in the press frame 21 as illustrated in Fig. 4. The pressplate 25 is carried by the press frame 21. By the manipulation of thescrew 28, the books 24 may be released from the hooks 19 by permittingthe press frame to be lowered.

In the operation of vulcanizing the press is clamped by means of thescrew 28, which causes the press frame 21 to be elevated and the hooks19 and 24 to engage. In this position suflicient clamping action may beapplied as required.

In Figs. 1, 2, 3 and 4 I have shown my vulcanizer cast integral with theexhaust manifold 9, whereas in Figs. 5, 6 and 7 I have illustrated aconstruction by means of which the vulcanizer may be applied to theexhaust manifold of engines already in use.

In order to attach the vulcanizer to an engine already in use, all thatis necessary is to form a hole 30 in the exhaust manifold, and applyaround the manifold the clip 31.

The clip 31 is provided with a screw threaded tubular extension 32 whichtapers, and by means of an internally screw threaded coupling 33, theclip 31 may be secured on the manifold.

In this case when the vulcanizer is applied to an engine already in use,the neck 1.1 is provided with a screw threaded end 34, which is screwseated in the coupling 38.

This form of connection does not weaken the exhaust manifold and forms atight joint preventing the escape of any of the hot gases.

Mounted in the neck 11 is a damper 35 for regulating the heat of thevulcanizer.

The vulcanizer maybe attached at any position of the exhaust manifold,or even on the exhaust pipe, if desired.

It will thus be seen I have provided a vulcanizer for hydrocarbonengines, which is heated by the exhaust gases of the engine, and iscarried by the engine, and always ready when the engine is in use, forvulcanizing purposes, no heating being required except that derived fromthe hot gases of combustion from the engine. The vulcanizer is compactand being formed integral, it is air tight, preventing the escape of anyof the gases. The bafiles located on the inside of the vulcanizer notonly perform the function of distributing the heat, but also act toretain the heat, preventing the vulcanizer from cooling too quickly.

Having fully described my invention, what I claim is:

1. A vulcanizer for internal combustion engines cast integral and formedhollow, a series of bafiie plates formed internally in the vulcanizerfor distributing and holding the heat, a connection for securing the vulCopies of this patent may be obtained for five cents each, by addreatingthe Commissioner oi Patents,

canizer to and placing the same in communi-- cation with the exhaustmanifold of an engine, a clamping frame pivotally secured to one side ofthe Vulcanizer so that it is capable of bodily movement to and from thevulcanizer, and a press plate carried by said clamping frame.

2. A vulcanizer cast integral, and formed hollow, a series of bafiieplates formed internally in the vulcanizer for distributing and holdingthe heat, a connection for securing the vulcanizer to and placing thesame in communication with the exhaust manifold of an engine, a clampingframe pivotally mounted on one side of the vulcanizer so as to be bodilymovable relative thereto, a press plate carried by said clamping frame,lugs carried by the vulcanizer, and lugs carried by the clamping frameadapted to engage therewith.

3. A vulcanizer cast integral and formed hollow, a series of baflleplates formed internally in the vulcanizer for distributing andretaining the heat, a connection for securing the vulcanizer to andplacing the same in communication with the exhaust manifold of anengine, a clamping frame pivotally mounted on the vulcanizer on one sideand provided on its opposite side with catches adapted to engage thevulcanizer, a press plate carried by said clamping frame, and a damperfor regulating admission of heat to the vulcanizer.

In testimony whereof I have signed my name to this application in thepresence of two subscribing witnesses.
